Disagreement among sources

When you read, you will soon find out that not all sources agree with each other. This is something very common. However, it doesn’t mean that one source is right and the other one is wrong. Contradictory sources are extremely useful for argumentative papers. They present opposing viewpoints that you need to address. These are some points you need to keep in mind regarding source disagreement.

  • Context: Check if there are any contextual factors like gender, ethnicity, age, etc. that influenced the way an issue has been researched.
  • Dated information: Sometimes the information is not wrong it is just outdated. The information may have been correct, when the source was published, however, newer research may have revealed new facts.
  • Different definitions: Different authors define terms differently. This may affect how authors develop their ideas on a topic and may eventually prove that they don't actually disagree, but present a topic from different angles.
  • Different interpretations: Different authors interpret data in different ways. Two authors may be analysing the results of the same research study, however, they may end up with different conclusions.
  • The presence of bias: Bias in research can be intentional or unintentional. Usually we associate bias only with personal values and beliefs injected in the information. However, failing to include significant facts, built logical arguments, and come up with concrete conclusions is also a form of bias.

Logical fallacies

A fallacy is an idea that a lot of people think is true, but, is in fact, false. It is a failure in reasoning or a false assumption, which makes an argument invalid. A fallacy usually confuses the reader or oversimplifies a point. You should try to avoid these kinds of errors in your own writing. Then your paper will be stronger.
